These debris flows cause serious harm to the mountain settlements, roads and nature reserves. This paper in order to exploration surveying and mapping, the debris flow terrain geology survey and mapping, typical section measurement, exploration and test of exploration scheme design，and then find out the basic characteristics of debris flow, emergency management for debris flow design scheme proposed.
